Richard Hebbert, the CPS lawyer who was in charge of the case comments on the guilty verdict handed down to Hannah Bonser for the murder of schoolgirl Casey Kearney:

“The manner of Casey’s death in many ways embodies the worst fear of every parent. Having set out to go to the house of a

friend early on Valentine’s Day afternoon, circumstances combined cruelly to put her in the wrong place at the wrong time. It was a pointless waste of a promising young life. The prosecution case showed from the outset that Hannah Bonser killed Casey and this was accepted by the defence.

The issue at trial was how responsible she was for what she did. The opinion of a psychiatric expert instructed by the prosecution to assess Hannah Bonser’s mental state was that whilst she was suffering from a personality disorder she was able to understand the nature of her conduct, form

a rational judgement exercise self-control and on that basis she would be guilty of murder. prosecution has been conducted on that basis and today the jury agreed with us. This has been a tragic case for all who have been touched by it, but, of

course none more than Casey’s parents, who, I hope, feel at least that justice has now been done for their daughter.”
